The K20 is the masterpiece of the flagship K Series. In addition to headroom in abundance even for the power-hungriest woofers, the most powerful member of the K Series comes preloaded with all options, making the K20 the ultimate powerhouse in every single aspect, yet packing it all into a single 19” rack unit weighing as little as 12 kg/26.5lb. Possible only due to remarkably high efficiency exceeding 85%, the enormous power density paired with unique Powersoft technologies warrants top performance despite running off a single mains phase. Like all K Series models, the K20 is designed for, and absolutely stable with, 2 ohm loads, further reducing the number of amps required to power a specific system.
